ELECTRIC BATTERY.

Specification of Letters Patent.

Application filed July 29, 1909. Serial No. 510,221.

Patented Dec. 3, 1912.

To all whom it may concern:

Be it known that I, GEORGE A. Ln'rz, a citizen of the United States, and resident of Plainfield, in the county of Union and State of New Jersey, have, invented certain new and useful Improvements in Electric Batteries, of which the following is a specification.

My invention has reference to improvements in the class of electric batteries employing a depolarizer comprising a plate of compressed metal oxid, such as cupric oxid, and a positive electrode, such as zinc. In the manufacture of such depolarizer plates difficulties arise in producing the same in asubstantially rectangular form owing to the fact that when such plates are removed from the compressing molds or dies there is danger of the edges of the plates becoming more or less broken or chipped, involving a considerable loss of material and labor, and there is a further difficulty experienced in that such compressed plates are not uniform in size after being baked, due'to the-shrinkage that takes place. Owing to such variations in the size of the baked plates, although the be formed in the same mold, difliculty g und in properly adjusting the supporting frames to the plates and making good contact therewith at various parts of the plates.

The object of my invention is to ,overcome the difficulties and objections set forth as well as others incidental to the manufacture and use of such battery plates, whereby the cost will be reduced, the handling of the parts will be facilitated, and the efliciency of the battery will be maintained or increased.

Incarrying out my invention I provide a depolarizer plate in annular or disk-like form, and apply a substantially circular or annular frame or, holder about the annular edges of the plate, with means for properly is a section substantially on the line 3, 3, in Fig. 1; Fig. 4 is a section on the line 4, 4, in Fig. 3; Fig. 5 is an inverted perspective view of the supporting insulating block for the electrodes; Fig. 5 is a sectional detail of a modification; Fig. 6 is a detail view of a modified form of the frame or holder for the depolarizer' plate, and Fig. 7 is "a section on the line 7 7 in Fig. 6.

Similar numerals of reference indicate corresponding parts in the several views.

1 indicates a j ar and 2 its insulating cover, which may be of any suitable construction. The depolarizer plate or negative electrode 3 is shown in annular or disk-like form of suitable thickness. Plate 3 is shown provided with annular beveled surfaces 3 leading to the periphery of the plate. A frame or hanger 4, shown made in channel form, is mainly in circular or annular form approximating the periphery of circular plate or disk 3 and fitted around the edge thereof, whereby good contact between said plate and frame may be made owing to the ability of said frame to be drawn snugly against plate 3 due. to the annular form of said frame. Frame 4 is provided with an extension having side members 4 spaced apart, by which said frame may be supported or hung. Frame 4 and its extension 4 may be made of a single piece of material as in Figs. 6 and 7 or said frame may be made of a pluralityof parts connected together, whereby the frame is readily attached to annular depolarizer plates 3 that may vary somewhat in diameter.

In Figs. 1 to 4 I have shown the frame as made in two separate parts each having an extension member 4 and means for connect-ing the opposite ends of the frame parts together. In this example each extension member 4" is provided with a laterally disposed finger or web 4 whichis adapted to lie one upon the other, (Figs. 2 and 3), and to be firmly held in position. I have shown said fingers provided with registering slots 4 adapted to receive a rod 5 which is shown provided with threads receiving a nut 6' for clampingv the fingers 4 together, whereby said fingers are adjustable and may be held in positions of adjustment, and electrical contact between rod 5 and frame 4 is effected. While with the construct-ion shown in Figs. 1 to 4 the lower part of frame 4 may be in a single piece, I have shown frame 4 divided in two parts .detachably connected together. For this purpose one member of said frame may have an ear 4 having an opening receiving projection 4 carried by the other member of the frame, the end 4 ofprojection 4 being bent'back against ear 4 to firmly clamp the frame upon plate 3. If preferred, the members of frame 4 may each be provided with ears 4' connected together by a screw or. bolt 7 for the same purpose, and a screw or bolt 7 may pass through extensions 4 to aid in holding the frame snugly against plate 3, see Fig. 6. The annular electrodes 3 may be made with little danger of breakage as they have no corners, and the arrangement of frames described is such that they may be clamped around the electrodes and drawn tightly to fit properly notwithstanding variation in diameter or contour of the electrodes that are made in the same or corresponding molds.

At 8 is an insulating block which is shown supported from cover 2 by rod 5, and said block supports frame 4, plate 3, and the positive electrodes or zines 9. Said block is shown provided with an upwardly disposed aperture through which rod 5 passes, and with a recess 8 in which the head of rod 5 is located. Block 8 is shown provided with a gain or recess 8 in its under surface in which the upper edge, of plate 3 is located. Block 8 isalso shown provided'with a recess or'gain 8 in its upper end within which the upper transverse portion 4 of frame 4 fits, and the nut 6 on rod 5 serves to clamp the transverse portion of frame 4 firmly in recess 8 against block 8. Block 8 is also shown provided with vertically disposedrecesses or gains 8 in which the side members of extension 4 of frame 4 fit or block 8 may have vertical ribs 8 on opposite sides receiving the channel extensions 4 see Fig. 5 The recesses 8, 8 or ribs 8? of block 8 serve to maintain frame 4 in proper position upon the block and prevent undue lateral movement of depolarizer plate 3. The positive electrodes or zines 9 are shown in disk form corresponding to the periphery of depolarizer plate or negative electrode 3, and said positive electrodes are shown provided with extensions 9 located at the sides of block 8 and secured thereto by screw or bolt 10 passing through extensions 9 and block 8 but out of contact with frame 4 and rod 5. Zines 9 are thus securely held in proper posit-ion with relation to plate 3 and insulated therefrom. Rod 5 is supported from cover 2 as by a block or head 11 detachably fitted upon rod 5,, or block 11 can be made integral with block 5 and the latc-iier be provided with a nut at its lower en As frame 4, the positive electrode, and the negative electrode or electrodes are supported by cover 2 by means of the insulating batteries, Serial No. 499,154, filed May 29,
